Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gate driver and source driver are configured in non-rectangular display devices, then the display device can achieve diverse shapes, but the configuration positions are limited and occupy pixel area, reducing light transmittance
Solution Approach 1:
The patent extracts the data line wiring from the traditional configuration and reorganizes it into a dual data line system with shared connections. By taking out the redundant wiring and consolidating it into shared data lines for sub-pixels of the same wavelength, the patent reduces the wiring area within the pixel structure, thereby increasing light transmittance while maintaining the non-rectangular display shape capability
Solution Approach 2:
The patent merges the data line connections by allowing sub-pixel structures corresponding to the same display wavelength to share common data lines. This consolidation reduces the total number of data lines needed, decreases wiring area occupation, and improves light transmittance while preserving the ability to support diverse display shapes through the gate driver configuration
2Ease of operation
If gate line configuration space is provided in vertical direction, then vertical feeding is enabled, but pixel area is occupied and light transmittance decreases
Solution Approach 1:
The patent changes the wiring arrangement from a traditional single-dimension layout to a dual-data-line configuration that utilizes both horizontal and vertical dimensions more efficiently. By implementing shared data lines that extend in multiple directions and connecting sub-pixels of the same wavelength, the patent enables vertical feeding capability while minimizing the area occupied within the pixel structure, thus improving light transmittance
